The statement that is true is the third statement: Layer A is the outer core and Layer B is the inner core.

Answer:

Option C, Layer A is the outer core and Layer B is the inner core.

Explanation:

The core of earth consists of two parts - outer core and inner core

The inner core of earth is made up of iron which exits at a high temperature equivalent to temperature of sun. The pressure at this layer is extremely high and thus the metal in this part of earth's core does not convert into liquid.  

While the outer core is made up of iron, nickel and other metals (in trace amount). As the pressure in this part of earth’s core is comparatively lower than that of inner core ,the metals exists in fluid form.

Thus, option C is correct

Which best describes oogenesis and spermatogenesis?
pochemuha
The answer is <span>B. In both oogenesis and spermatogenesis, the cells become haploid after meiosis I.

Gametogenesis is a process in which gametes are produced. Oogenesis is a process in which egg cells are produced and spermatogenesis is a process in which sperm cells are produced. Both processes include meiosis.
Original diploid cell (primary oocyte or spermatogonium) has 46 chromosomes. After meiosis I, there are two haploid cells. After meiosis II, there are 4 haploid cells because meiosis II is similar to mitosis. The difference between spermatogenesis and oogenesis is that those 4 cells after meiosis II in spermatogenesis are all sperm cells, and in oogenesis only one of them is egg cell.</span>
